The present invention relates to a fob learning method using a low frequency signal and a radio frequency signal, which includes a first step in which an engine controlling device enters a learning mode; a second step in which at least one fob receives a learning mode entering order from the engine controlling device via low frequency communications and enters the learning mode; a third step in which the fob receives a fix code reading order from the engine controlling device via radio frequency communications, selects one out of time slots separated in a set number, and responds to the engine controlling device with the fix code; a fourth step in which the engine controlling device sends information indicating searching completion of the set number of fobs to a diagnosing unit with all the fix codes to be learnt received from the fob; a fifth step in which the engine controlling device checks the default secret key value of a fob with a corresponding target fix code among the fobs and sends the secret key value and the fix code to be learnt to the fob if the checked default secret key value is identical to a set default secret key value; and a sixth step in which the engine controlling device receives a confirmation response from the fob with the corresponding fix code and responds to the diagnosing unit that the fob learning has completed. According to the present invention, the virgin fob learning process through a fob holder can be successful even when the fob is not placed at a specific position. Therefore, the learning becomes easier as the user needs not to tag and hold the fob to a fob holder. |
